Am not sure they did so poorly. Sure, 5,7% isn't a landslide, but in the election 2006 they only had 2,9%. So I guess it depends on perspective, you can see them as "only" getting 5,7%, or you could say that they doubled their size.

Also remember that this is in Sweden, the political debate is mainly done in state controlled media, and what isnt state controlled is usually tagging along the bigger channels regardless. So, for a party completely shushed down to get more than one vote out of twenty is rather well done.

And as mentioned, this is the beginning, they will probably grow in size and support now they are sitting in parliament and can get their issues discussed properly.

Thank you for the welcome :)
